figure 6
Belaying to a mooring bollard or samson post secures a ship to shore.
Take a series of turns around the post, and pass a bight of rope under the
(loadbearing) standing part and then drop it over the turns on the post
(figure 7). You can take the end around the post again, and pass another
bight under the standing part to drop it over the post. You can repeat the
process again, but on no account should you take a turn around the post
with the standing part.
